Cutaneous melioidosis: An updated review and primer for the dermatologist.

Melioidosis is an emerging infection with increasing endemic foci and global distribution. It is underrecognized and underdiagnosed because of factors including limited awareness of the disease, nonspecific clinical presentation, lack of diagnostic facilities in some locations, misidentification in laboratories inexperienced with culture, and identification of Burkholderia pseudomallei. Cutaneous findings are reported in approximately 10% to 20% of melioidosis cases and dermatologists may play a significant role in its recognition and management. The most dynamic situation of melioidosis recognition and/or expansion currently is in the United States. Global modeling had predicted that B. pseudomallei were potentially endemic in the southern United States and endemicity with local cases of melioidosis was confirmed in 2022. With the distribution and prevalence of melioidosis increasing globally and with this recent recognition that melioidosis is now endemic in the southern United States, it is important for dermatologists to maintain high clinical suspicion in appropriate patients and be familiar with its diagnosis and treatment. Here we review the available literature on cutaneous melioidosis to evaluate its epidemiology, etiology, pathophysiology and clinical presentation and provide guidance for diagnosis and management in dermatology practice.
